Abstract:
This study reported the complete nucleotide sequence of the Nicotiana tabacum TN90 chloroplast (cp) genome. The cpDNA was 155 992 bp in length and contained 133 individual genes (79 protein encoding genes, 30 tRNA genes and four rRNA genes). Maximum-likelihood (ML) phylogenetic tree for 17 species with Arabidopsis thaliana, Oryza sativa, and Anomochloa marantoidea as an outgroup resulted in a single tree with - lnL =542 222.71, where the Nicotiana tabacum TN90 plastid was clustered with three previous reported Nicotiana species: N. tomentosiformis, N. undulata and N. tabacum. The TN90 variety of tobacco cp genome sequence reported in this study will accelerate tobacco improvement in the future.
